Compare the proposed diagnosis and scope before the score. Branch listings keep separate observations, and a company service claim does not determine the right repair for your property. Source dates and ranking limits.

Compare the diagnosis and repair scope
A score cannot determine what your foundation needs. Compare the written findings and proposed scope before comparing totals.
- Assessment: Ask for the observed conditions, proposed cause and basis for the recommended work.
- Repair scope: Request the locations, products, work steps and exclusions in writing.
- Project responsibility: Identify who evaluates the problem, performs the work and handles any additional specialist input.
- Terms and follow-up: Compare payment terms, written warranty conditions and the follow-up process.
Scope and branch limits
This category requires advertised repair of existing residential foundations. New-foundation construction, flatwork or concrete lifting alone does not establish that service.
Listing locations identify the observed records. They do not establish a staffed office, a company's full service territory or availability at your address. Confirm those details directly.
How we rank and what we checked
This edition accounts for 122 held listing IDs from an earlier Maps collection covering several markets. It is a bounded Kansas City review of those records, not a fresh comprehensive metro search. Nine exact listing IDs have October 28 observations; the remaining 113 retain October 24 observations. All identities remain separate. Selected listings, the next eligible cutoff where present and unresolved records above the selected cutoff receive focused service and identity review. Accounting for every record does not mean every lower pending case has complete source evidence. 14 currently qualify, and the 10 highest-scoring eligible listings are shown. 9 unresolved candidates have higher potential scores than the last selected listing and could change this order. Missing evidence is not a conclusion that a company lacks the service. An additional eligible listing was checked immediately below the selected cutoff.
This category requires advertised repair of existing residential foundations. New-foundation construction, flatwork or concrete lifting alone does not establish that service. Eligibility also requires a matched listing, a working company website, a rating of at least 4.0 and at least 10 reviews. Unresolved service or branch evidence remains pending. No listing reviews are merged.
Google observation dates are shown on each entry and remain tied to the exact listing ID. Company descriptions are advertised service claims checked on the entry's separate service date; they do not certify licensing, insurance, workmanship or availability. Website review widgets do not replace the dated Google observations. Review recency was not measured.
Local Score = (15 × 4.5 + reviews × rating) ÷ (15 + reviews). The prior is an editorial choice, not a measured local average. Full-precision results determine order, with review count, case-insensitive company name and place ID breaking ties. Displayed scores are rounded to two decimals. Small score differences do not establish a workmanship difference.
Credentials, sponsorship and business relationships add zero points. Business relationships neither qualify nor disqualify a company under the service and evidence rules. Publication methodology · Request a correction.
